Here, however, the components are connected irreversibly and expensively
Furthermore, the air spring damping systems known from the prior art have the disadvantage, inter alia, that the relative rotation of damping tube and air spring is not restrained with sufficient safety.

Embodiment Construction

[0031] figure 1 A schematic view of an adapter piece 1 according to an embodiment of the invention is shown. Here, in the illustrated embodiment, the adapter part 1 comprises an elastic spring region 2 comprising a total of four subregions 2' or spring elements 2' (due to figure 1 Three of them can be seen in the perspective view selected in ). Alternatively, a different number of subregions 2 ′ or pressure pads is also conceivable. The spring region 2 (or its subregion 2 ′) can be compressed by a normal force acting radially in the direction of the center of the adapter part 1 . In the exemplary embodiment shown, the subregion 2 ′ comprises in each case two recesses or holes and is configured as a pressure pad. The recess is mainly used to save material and to configure the same wall thickness. Alternatively, other geometries are also conceivable for the subregion 2 ′. The inner wall 5 of the adapter part 1 is located radially on the inside. The first annular area 3 is ...

Abstract

The invention relates to an adapter piece, an air spring damping system and a method for producing the system. The invention relates to an adapter part for the non-positive connection of a damping tube and an air spring piston, the adapter part comprising a spring region.

Description

technical field [0001] The invention relates to an adapter piece for non-positively connecting a damping tube and an air spring piston. Furthermore, the invention relates to an air spring damping system comprising a damping tube and an air spring piston and a method for producing an air spring damping system of this type. Background technique [0002] Air spring dampers are used in suspensions and in the damping of vibrations / bumps acting on the vehicle and are notably characterized by a high degree of flexibility in the setting of the prestressing force. In this way, the height of the vehicle body can be adjusted or set, for example by means of an air suspension system. [0003] Arrangements are known from the prior art in which a rolling piston or an air spring piston is fastened directly to the damping tube, for example by welding. Here, however, the components are connected irreversibly and expensively. Furthermore, the air spring damping systems known from the prior ...
